Running the NFC Text record routine on nRF5340 DK, the mobile phone NFC cannot scan the tag

[JFMSAE]

Hi，I have some problems using the NFC routines in the SDK.

The hardware used is nRF5340 DK.

Software is nRF Connect SDK v2.6.99-cs1.

The downloaded and run routines include: Launch APP, Text record, TNEP tag.

After downloading the three examples to nRF5340 DK, I can see that the log is printed normally, but the mobile phone NFC cannot scan any response.

I can confirm that the NFC antenna and my phone are fine, and the same is true for both nRF5340 DKs I have.

At the same time, I have an nRF52840 DK and downloaded the routine program into the mobile phone NFC, but it still cannot scan.

However, when using the NFC routine in the software nRF5 SDK v17.1.0 on the nRF52840 DK, the mobile phone NFC can scan the NDEF message.

But I need to use nRF5340 to implement NFC tag function.What could be the problem that causes the NFC tag routine to be unresponsive when running on the nRF5340 DK?

Or do I need to set some special configuration in the SDK?

Hello,

Please try to flash the hex file attached below and see if you get the same result. It's the record_text sample from SDK v2.6.1.

Pre-compiled hex:

0257.zephyr.hex

nrfjprog --program zephyr.hex --chiperase --verify -r

Software is nRF Connect SDK v2.6.99-cs1.

Please use v2.6.1. v2.6.99-cs1 is only intended for those who were participating in the nRF54L15 customer sampling program.

Best regards,

Vidar

Hi，thank you for your reply.

After I burned the hex file to nRF5340 DK, the mobile phone NFC can scan the tag. But the version number printed in the log is v3.5.99-ncs1-1.
So according to what you said, I should use SDK v2.6.1, right?

Hi,

I was using v2.6.1 to build this FW, but there is a bug in this version that sometime causes the wrong version number to be printed. In this case, it is printing the Zephyr version included in this SDK release.
